PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

Amorphous titanium dioxide nanotube anodes for sodium-ion batteries show ability to self-improve specific capacity

Green Car Congress

A team of researchers at the US Department of Energy’s Argonne National Laboratory has synthesized amorphous titanium dioxide nanotube (TiO 2 NT) electrodes directly grown on current collectors without binders and additives to use as an anode for sodium-ion batteries. V vs Li/Li + ) with comparable capacities to the dominant graphite anodes.

Researchers find tin nanoparticles promising electrode material for sodium-ion batteries

Green Car Congress

Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
